ENGINE.

englne in which a mixture of air or oxygen and the fumesfrom oil is employed as fuel, which is projected into a combustion chamber located within a steam boiler, in which combustion chamber the pressure thereinis greater than atmospheric pressure, and by the explosion of the fuel, asit is projected into the combustion chamber, the water in the boiler and about the combustion chamv ber is heated to a great temperature, in order that the. steam therefrom may be employed for running an engine, used in conjunction with .the present invention, the detail structure of which will be hereinafter thoroughly described.v

One of the objects of the invention is to provide an air compressor of a two cylinder type, whereby air may be drawn therein, compressed in alow pressure cylinder, and then ejected into a high pressure cylinder, where it is again compressed and forcedor delivered into the vair reservoir. lFrom the ,air reservoir, a certain portion of the air ascends through a pipe or tube to an oil or fuel tank, above the level `of the oil, so that the oil may be forced downward to that point where it may be vaporized by air or oxygen from the reservoir, and projected into the combustion chamber, in the form of combustible gases. The fuel used may be crude oil or petroleum, or any other suitable or similarfluid.

Another object of the invention is the provision of means or a power cylinder, into which the products of combustion from the combustion chamber, after passing throu h the iiues of the boiler, are delivered, in or er that the piston of the power cylinder may be operated, which, in turn, operates the air compressor, through the medium of the rod connection. As hereinbefore stated, an engine of the` steam type lis utilized in conjunction with the rod of the power cylinder 4and the air compressor, 1n order to assist in Specification of Letters Patent.

the thorough operation of those parts s aid engine of the steam type, as shown, receives its supply of steam from the steam-boiler of the gas engine, there being a suitable Water sulpply for said steam boiler, and valso an oi supply for the'fuel' tank.

In this specication and the annexed.

drawings, a particular` design of device is adhered to, but the invention ',is'not to be confined to thisspecilic design. The device in its actual reduction to practice may necessitate changes and variations, the ri ht thereto belongs to the applicant, provied such changes and variations are -comprehended by the a pended claims.

To obtain a full an correct understanding of the details of construction, attention is directed to the4 accompanying drawings, the structure therein being described by this specication, and in which drawings- Figure 1 is a vertical sectional view through the gas engine, showing the interior structure of the boiler, the combustion chamber,-

and the .power cylinder and air compressor; in this figure an engine of the steam type is shown in connection with .the gas engine. Fig. 2 is an enlarged sectional detail view through the air compressor. Fig. 3 is an enlarged sectional view through the power cylinder, which, in Fig. 1, is shown as coupled in conjunction with the air compressor, receiving) the products of combustion from the com ustion chamber. Fig. 4 is a top plan view of the gas engine, showin the various operating parts in elevation, an further illustrating the engine A coupled therewith. Fig. 5 is a sectional view upon line 5 5 of Fig. 1, showin the construction and location of the lines o the boiler. Fig. 6 is an enlarged detail view, showing the connections between the fuel tank, the air reservoir and the rear portion of the' steam boiler. Fig. 7 is an enlarged det-ail view of the elbow connection 1G, between the pipe 12, the pipe 15 andthe fianged pipe 24,"showing the defiector plate 21, and the perforated block or partition 18 (which consists of the two parts 19 and 20).

Referring more essentially to the detailed los l structure of the gas engine, 1 represents a steam boiler, which may be of any desired of the boiler casing is an inner .casing 3,y

consisting of two sections 4 and 5, between l which sections 4the heat-ing tubes are conv instance the greater part thereof, is utilized as a combustion chamber 6, in which is'located a partition or section or body, which V becomes incandescent under the heat of the flame or under the heat from the combustion of the gases. This partition, section or body 7 may be of various forms and materials, but in the drawings it is shown as being made or constructed .of lire clay or brick or the like. As this partition, section or body becomes incandescent, after the gas engine is under way, the fuel or gases as they enter the combustion chamber are easily and readily united. Between the inner and outer casings of the boiler, a water space 8 is provided, which receives its supply from any suitable source, for instance as shown at 9. Leading from the outer casing of the boiler is a steam pipe 10, which communicates and connects with the steam chest a of the engine A, in order that the evaporation of the water in the boiler .may be used for furnishing power to the eng' p 1ne A. 11 represents t 1e oil fuel tank, from which a pipe 12 extends, and to the upper portion of which an air supply pipe 13 connects, in order that air may be supplied above the level of the oil or fuel, in order'that the oil -or fuel may be forced through the pipe 12.

This air supply ipe 13 extends from and communicates wit the air reservoir 14. Extending upwardly from the reservoir 14 is a short pipe 15, to which is coupled the elbow connection 16, which forms communication between the combustion chamber, the air reservoir, and theV pipe 12. This elbow connection 16 is provided with a mixing chamber 17, in which is located a perforated block or partition 18, consisting of two arts 19 and 20, the purpose of which is to a low the combined fumes or gases from the oil and the air or oxygen to mix and pass therethrough, but the part 20 of said block or partition prevents the iames in the combustion chamber from reaching the mixing chamber in the elbow connection 16. Projectin laterally from one of the walls of the mixing chamber 17 is a deflector plate 25 is located between the inner and outer tion 16 is also anged, as at 28, and is bolted to a flanged portion 29 of the pipe 15, and at this junction, and preferably located in a portion of the pipe 15 is a check valve 30, which prevents back lpressure of they gases or the combined fumes from the oil and air or oxygen from entering the air reservoir.

31 represents an air compressor comprising a low pressure cylinder and a igh pressurecylinder 32 and 33. Extending through the cylinders is a piston rod 34, at two locations thereon pistons 35 and 36 are arranged. The piston 35 operates in the low pressure cylinder, while the iston 36 opcrates in the high pressure cy inder. These low pressure and high ressure cylinders are provided with suitab e packing glands 37 and 38, through which the 1piston rod 34 extends. The low pressure cy inder is provided with two air inlets 39, which are controlled by spring-tensioned valves 40 and 41, which valves alternately open and close. In other words, as the piston 35 moves in the direction of the arrow 42, the valve 41 is opened, in order to draw a supply of air, and the air in front of the piston 35, when the same is in the position shown in Fig. 1,

closes the valve 40 and opens the sprmgtensioned valve 43, (which is located 1n the casing 44), and by the opening of the valve 43, the air in front of the piston 35 is forced into said casing 44 and through the pipe 45. When the piston 35 is operating in the reverse direction, or in the direction of the arrow 46, a similar cycle of operations 1s accomplished, but Wit one exception, and that is, the valve 47 is opened, as well as the valve 40, and the valve 41 is closed. When the valve 47 is opened, the air passing thereby is also forced into the casing 44, and

, through the pipe 45.

The pipe 45 communicates with the casing, 48, of the high pressure cylinder 33. The high pressure cylinder 33 is similar in construction to the cylinder 32, there being similarly operated valves, designated by the numerals'50, 51 52 and 53, all of which are spring-tensioned, as well as the valves 40, 41, 43 and 47. The operations of the parts of the cylinder 33 are similar to those of the cylinder 32, but with the exception that the air as it reaches the casing 54, is delivered or forced through a pipe 55 and into the air reservoir 14, under extreme high pressure. The cylinder 33 is smaller in diameter than the cylinderA 32, therefore, when the air reaches the cylinder 33, the same is considerably more compressed.

56 designates the means or power cylinder (the piston rod 57 of which is coupled with the piston rod 34 of the air compressor), and furnished power for the air compressor. This means or power cylinder 56 is provided with theus'ual water jacket 58, and connected with the power cylinder there are three more to o l are designate is a pipe 59, which communicateswith the inner casing, or rather the interior of the inner casing, of the steam boiler, forward of the heating tubes, so that as the products of combustion from the combustion chamber, emanate from the heating fiues may reach the means or power cylinder 56, and in rear or in front of the piston 59a (which piston 59a is carried by thepiston rod 57.) The products of combustion pass through the pipe 59 with suilicient force to reach the chamber 59b between the valves l60 and 61 (which alternately open or close by means of the rocking shafts 62 and 63.) These rocking shafts are provided with upwardly extending arms 62EL and 63, which'are oonnected with the valve rods 61% To operate the rocking shafts or rods 62 and v63, a shaft 64 is provided. This shaft 64 is mounted in suitable bearings 64a of the base of the apparatus. To transmit power to thel shaft 64a', the same is provided with a beveled gearing 64b, which is in mesh withthe beveled pinion 64?. This pinion 64c is rotatable with the shaft 64c1 (which is mounted in bearings 64e). The shaft 64d is provided with a beveled pinion 64g, which is in mesh with a beveled gear 64h (which is rotatable -withthe shaft 79.)

Mounted upon the shaft 79 is a suitable,

fly wheel V79a and two disks 80, which are connected by pitman rods 81, to the piston rods 34, clearly shown in Fi 4 of the drawings. One of the piston rods 34 is connected by a pitman rod 34n to the engine A, in

order to assist the Apiston rods 34 in' their` operations, and, therefore, assist the power cylindersin their operations. The shaft 64b is provided with a plurality of cams, there being six in number, three to operate the various valves of one power cylinder, while rate the valves of the opposite dpower cylinder. These cams by the characters 65, 66 and 6 7. The cams 65 are engaged by anti-frictional members 68, which are carried by the oscillating arms 69". These arms 69 are mounted to move with the rods orshafts 62 and 63, which operate the valves 60. It willbe noted that as the shaft 64 rotates, the cams 65 also revolve, which raise and lower the arms 69a. By this operation, the valves are o ened and closed. The arms 96a are raise against the/tension of the springs 69", and upon the reaction of the springs the arms are lowered. The cams 66 are engaged by the frictional members 66, which are carried by the rods 66". slidable in guids 66, and are spring-,tensioned by means of the spring 66d. The ends of the rods 66h, opposite the ends carrying the frictional I nembers66a are connected to the arms 66.` These arms are movable with the other two'rocking shafts 62 and 63, asshown clearly in Figs. 3 and It These rodsl 66b are' will be clearlynoted that the various valves of the upper portion of the power cylinder are alternately operated by the above described mechanism.

To operate the exhaust valves 68v and 69, the rods 70 and 71 are connected by the links 7 0 and 71", .which are connected to the arms` Movable with 7 0b of the rocking shafts 70C. the rocking shaft 70c are arms 70d, and connected to these arms are rods 70e.v These rods 7 0e are provided with enlargements 7 0, having slots 70, through which the shaft 64 extends. These enlargements are disposed adjacent the cams 67, andv mounted upon stud shafts of these enlargements are antifrictional rollers 70k, which ride about the periphery of the said cams, in order to impart a reciprocating motion to the rods 70e, so as to rock the 'shaft 70e. These rods 70 alternate in their movements, for instance, as one of the rods is moving rearwardly and downwardly, the opposing rod is moving forwardly and upwardly, As the valves 68 and 69 are operated, an exhaust of the products of combustion is readily had through the casing 72 and pipe 73.

The portions of the power cylinder through which the piston rod 57 passes, are provided with packing glands 74 and 75, in order to prevent the escape ofthe product of combustion. The pipe 59 is provided with a water jacket 76, which water jacket The water jackets of the power cylinder and the air compressor are provided with pipe connections 83 and-84 with the water supply tank 9, as shown clearly in Fig. 1, there being a suitable connection 83 between these pipe connections and the steam boiler. The'connection or pipe 84 is rovided with a check-valve 87, vwhich c oses automatically when the Asupply is cut off by the valve 89. The connection between the water supply and the steam boiler is provided with a valve 89a, the purpose of which is to cut off the water suppl from the steam boiler when it is so desire If at any time it is for otten to shut oif the valves 89 and 89B, an the water iows continually until it backs against the check valve, the back pressure of the water will 'in the high compress cylinder, it isu forced into the reservoir. The piston rods and ioo pistons are operated through the medium of the power cylinder, and are also assistedv in their operations by means of the engine A (which receives its generation of steam from any suitable source not shown, as indicated at 89g.) This engine A also receives its generation of steam from the steam boiler.

By forcing a high pressure of air into the reservoir, a certain ortion thereof passes through the pipe 13, but the greater portion thereof passes through the check-valve in the pipe 15 into the mixing chamber 1T, where it thoroughly mixes with and vaporizes the supply of oil from the pipe 12, at the point where the perforated block or partition 18 is arrange The certain amount of air which goes through the pipe 13 enters the oil or fuel tank 11 above the level of the oil or fuel, and causes the oil or fuel to flow through the pipe 12, and when the supply of oil reaches a point adjacent the perforated block or partition 18, it. strikes the deector 21, Where it is broken into particles of infinitesimal size. These small particles are easily and readily vaporized, and when the fumes are thoroughly mixed with the air, 'a high explosive mixture is produced, which is pro]ected into the combustion chamber, and as this mixture reaches the artition, section or body 7 (which becomes incandescent from the heat lof the iames), is i nited. After this explosive mixture is ignited, the products of combustion therefrom are conveyed through the heating ues of the steam boiler, and conducted through the pipe 59 and to the power cylinder 56,

where it is utilized for operating the piston 59, the piston rod of which, in turn, operates or assists in operating the compressor. From the combustion of this explosive mixture, an intense or extreme heat is produced, which, together with the products of comf bustion traveling through the heating iues, heats the waterin the water space suic'iciently to generate the proper amount of steam, whereby the engine A may be supplied with a supply of steam. The pressure, as hereinbefore stated, within the combustion cham# ber is considerably reater than atmospheric pressure, and by t is great rassure, sufficient power is produced, in order to properly manipulate the piston 59a.
